Detector unit for position control
- Generates A/B phase output signal with a resolution of 0.5 µm for feedback to an NC unit and up/down output signal for a display unit.
- Selectable resolution and output pulse width
- Compact design of 32 x 171 x 144 mm / 1.3″x 6.7″x 5.7″ (W x H x D) permits the detector to be located in tight spaces as in a switchboard.
- Operable from 5 V power supply. With the optional PU20 power supply unit, power for up to 3 axes can be supplied.
- 2-axis addition available with the analog addition unit MW10.
- A/B phase signal, up/down signal, zero point signal and alarm signal output by differential line driver.
